In the deterministic context a series of well established results allow to reformu- late delay differential equations (DDEs) as evolution equations in infinite dimensional spaces. Several models in the theoretical economic literature have been studied using this reformulation. On the other hand,...

We study the compatibility of the optimal population size concepts produced by different social welfare functions and egalitarianism meant as “equal consumption for all individuals of all generations”. Social welfare functions are parameterized by an altruism parameter generating the...

This paper aims at analyzing the relationships between teamwork, autonomy and individual evaluation interviews. Within an agency model with teamwork, we show that a production technology characterized by strong horizontal interdependencies and super-modularity does not ensure coordination within...

Dix-sept pays européens ont adopté un revenu minimum garanti fonctionnant sur une base non contributive et différentielle. En théorie, ces mécanismes sont pleinement efficaces dans la lutte contre la pauvreté monétaire dès lors que le plafond de l’allocation est au moins égal au seuil...

This note proposes a full description of the Calvo price-setting model based on partial prices indexation and studies the interaction between partial indexation and trend inflation. We show that to use a hybrid version of the Phillips curve partly decreases the risks of overestimate due to the...

Nous explorons d’un point de vue microéconomique, à la fois théoriquement et empiriquement, les liens entre le renouvellement des générations et la dynamique technologique de l’entreprise en tenant compte des asymétries de position qui caractérisent les différentes générations et...

This paper examines whether patenting increases the private incentives to innovate in manufacturing. To study this issue, we build a model in which the value of an innovation depends both on the type of innovation implemented (product, process) and on the existence of a patent protection or not....

L’objectif de cette étude est d’évaluer l’incidence des mesures d’allégement de cotisations sociales sur les bas salaires à partir d’un panel sectoriel (NAF 16) et sur les vingt dernières années. Le modèle de portée général décrit l’impact du progrès technique biaisé, de...
